Option 1: 

Buy strengthened brass gears + hi-torque motors in quantity of 1 set for 1 mirror or 2  sets for both mirrors ($49.99 / $89.99). Requires 24 hour epoxy of brass gear onto main shaft in your unit.  You will re-use your existing main shaft and epoxy on a new brass gear section.


Option 2:

Option 3:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units e have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can buy the gear/motor combo for one of both sides, and with the spur gear pre-attached to a new main shaft, or loose. Loose gear orders require installation of the spur gear onto the main shaft using 24 hour epoxy - please refer to the DIY article link above.  We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

  1. Right solution for Power Mirror 5 Star Review

    Posted by on 6th Jul 2021

    My wife's Yukon 2010 stop folding on driver side. it makes hard to park inside garage. I find this "" from Youtube. I order pre-mount gear which save me time to wait for installation. The part is perfectly replace original damaged plastic gear. Instruction video is very detail which help me dissemble and install mirror glass. It is the best solution for your power mirror issue. Plus, shipping is very fast.

  2. Well worth the $ 5 Star Review

    Posted by on 3rd Jul 2021

    It's not an easy job but the instruction video is excellent. My second side was much easier than the first.

  3. Outstanding product 5 Star Review

    Posted by on 25th Jun 2021

    This is an outstanding product. I would recommend it to anyone. I just bought the gears and motors and spent the $10 so they came already to go. Don’t let let steps fool you, it’s not that hard and even my wife joined in. Most important thing is before you take the motor off the truck, mark the base in reference to the window. That way as you disassemble and reassemble you can constantly check the function. Awesome product. Wife’s very happy now!!

  4. Very easy repair 5 Star Review

    Posted by on 18th Jun 2021

    I bought two of the rebuilt folding mirror motor assemblies and was easily able to replace in my 2013 Avalanche using the provided instructions and you tube DIY videos available. Parts were exact fit and work like a charm. Very satisfied.

  5. GMC truck folding mirror gear 5 Star Review

    Posted by on 7th Jun 2021

    The gears are of high quality and much more stout than the nylon originals that broke. My only concern that one side of gear shaft was too large for brass fitting which was part of old gear. Tried to enlarge fitting and split. Using Drexel ground down to appropriate size and worked with no problem. Relatively easy fix and saved a lot of money. Gear is nosier as expected. Video was easy to understand.

  6. Excellent quality and great repair documentation!!! 5 Star Review

    Posted by on 21st May 2021

    Had to repair the broken plastic gear in my wife's 2012 - Traverse passenger side folding mirror. The documentation and video on how to repair the motor was excellent and I found the details on removing the Traverse/Acadia mirror elsewhere as it's a little different from the Suburban and Trucks. The repair went smooth and was able to easily pull the motor from the housing still attached to the vehicle. Everything went good and it works perfectly now. My only complaints are the mirror is much faster now than the OEM geared one - LOL and also it's quite a bit nosier. I'd assume the noise is due to the brass/metal gears vs. the stock plastic gears, but not that big of a deal.

  7. Quality gear and motor 5 Star Review

    Posted by on 17th May 2021

    I chose to buy the gear and go torque motor. Received the parts today and immediately went to work. The process on my 2014 GMC Sierra was similar, BUT not the same. The sequence of tearing down my mirrors was different, as well as my gear box. My gear box was a three piece unit, with the top and bottom being plastic! I was able to make the new gears work, but not with a lot of cyphering. If you are not fairly mechanically inclined, I suggest you buy the entire rebuilt gear box. Gruvenparts, are you aware that there are plastic gear boxes out there? You may want to address that in case you get one returned as a core. All in all, great product.

    -- response --

    Thanks Matt. The only real difference in the drive unit is the 2014+ pick up trucks got a plastic top cap and use a circuit board. The bottom of the unit including ALL gears and motor is same as previous gen. Glad you got it all working and let us know if you need more.

  8. Easy to install 5 Star Review

    Posted by on 15th May 2021

    Watched the install video, had it on while I installed.
    Everything went good, installed in about an hour.

  9. works great, communication and shipping could be better 5 Star Review

    Posted by on 12th May 2021

    The photos and step by step instructions and the parts are great....but...communication lacks.
    Ordered on 4-15-21 opted for UPS shipping, on 4-19 I received message it had shipped, short time later another message that it was scheduled for shipment. No movement on tracking number for 2 days so I messaged on 4-21 about status, received this message "Im sorry for delay on this. We are currently machining more of the integral gears and should be done Friday or Saturday and will ship as soon as finished" this would be April 23 or 24. If it shipped the next business day would be the Monday 26th destination is about 8 hours from Atlanta would not take UPS till Friday 30th to deliver. Received the request to review on 4-26 received the parts on 4-30. Seems like there would be a few on hand to ship when requested, I had the mirror off trouble shooting and had to put it back on and take it back off because it took so long for the parts to arrive.

    -- response --

    Sorry for this. We typically dont run out of integral gears but these are anything but typical times. The material shortages are hitting everyone and the mill just would not deliver the steel for us to cut the spirals. Very frustrating as we had people sitting around with nothing to do since no material could be had. Hopefully this administration gets this under control, we better start getting truck drivers again. We're fully in stock now but that was an unfortunate pain caused by the current supply chain dilemma across the board on just about anything you buy right now ... however our communication should NEVER be an issue, please let me know and I will do my best. In this case we were just being told multiple stories from the mill so I relayed lots of info that was constantly changing.

  10. Works perfect! 5 Star Review

    Posted by on 11th May 2021

    Watched a youtube video, looked at the installation pictures at Gruven. Was straight forward to change, took a little longer than 1 hour. Works perfect!
